Omnitronics is a well established electronics manufacturer in Australia and is a leading designer and manufacturer of electronic solutions for Interoperability Radio Communications, Communications Management and Control. They are renown for providing cost effective solutions for both the operation and management of radio networks. They are also a key supplier of radio-based telemetry and have developed specialised monitoring and control systems for a broad range of industries.
With 25 years experience in the provision of both off-the-shelf hardware and customised solutions, the Omnitronics name has become synonymous with cost-effective, flexible and reliable products.
Interconnect VHF and UHF radios sourced from different manufacturers or with different electrical interfaces.
Each device in the 619 Range has ports that support four-wire audio with E & M signalling. The audio ports are balanced with 600-Ohm transformer coupling. Besides providing isolation between devices and virtually eliminating ground noise, the audio ports allow connection to both balanced and unbalanced equipment. The E & M pins can be configured to work with any COS and PTT combination of the radio equipment. They provide isolation and can be configured for relay control or opto (voltage) input/output. Links also allow both inputs and outputs to be configured to source or sink power.
619SRI Smart Radio Interface
The 619SRI is an eight-port radio communications and configuration hub that is designed to provide cost effective interoperability between radios from different manufacturers and with varying signalling requirements. Using Omnitronics' proprietary technology, "DHC" (Dynamic Hub Configuration), the 619SRI brings together CTCSS, in-band keying, VOX, SELCAL and DTMF with a number of programmable configuration overlays. This provides users with the ability to dynamically configure radio networks to suit operational requirements and, through a Windows graphical user interface, makes radio interconnection easier than ever before.
The primary function of the Audio Bridge is the combining and linking of repeaters, links and other audio sources at remote sites. The 619EI have 6 ports and the 619GI have 4 ports.
The IPR100 is designed to provide Voice over IP extensions for analog radio equipment. Each device enables an analog two-way radio to be remotely controlled over an IP link, either in a LAN or WAN environment. Working in pairs, two IPR100 units can be used to create a back-to-back IP link between two radios. Alternatively, a pair of units can also be used to provide remote control and monitoring of a single radio from an operator’s handset or console.
Remote Radio Access using the IPR100 Voice over IP Adaptor
An operator can control and monitor a remote transceiver across a Local Area Network or a Wide Area Network. The transmit and receive audio, along with the PTT and Busy/COS signals, are transported over the link transparently, using VoIP Multicasting techniques. SELCAL and DTMF are also transported reliably, regardless of the level of compression that is employed.
UHF/VHF Link Replacement using the IPR100 Voice over IP Adaptor
Two radios can be connected back-to-back over an IP link. This can typically be used to interconnect two repeater sites over a Wide Area Network. PTT and COS signals are transported over the link as data messages. The IPR100 will provide a configurable PTT output to the radio. It will also accept a configurable COS input from the radio. An active COS signal from the radio will enable the transmission of voice packets over the IP network and generate a PTT output at the opposite end. Full duplex operation is supported.
Leased Line Replacement using the IPR100 Voice over IP Adaptor
Two audio devices, such as 4-wire audio bearers, can be connected back-to-back over an IP link. Since the communications equipment will not provide a COS output, a VOX function is implemented in the IPR100 using the VAD (Voice Activity Detector) feature. When a voice signal is detected at the radio port of the IPR100, an internal COS signal is generated and transmitted to the destination IPR100. This will also enable the transmission of voice packets over the IP network. A hang period is automatically applied to the VOX algorithm. Full duplex operation is supported.
